来自同事_Smile的封装应用,记录学习一下
1、AnimImageViewLoader类的封装
/**
* 适用于animation-list 动画
* Created by _Smile on 2016/6/13.
*/
public class AnimImageViewLoader extends ImageView {
private AnimationDrawable frameAnimation;
public AnimImageViewLoader(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public AnimImageViewLoader(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public AnimImageViewLoader(Context context) {
super(context);
init();
}
/**
* 初始化动画信息
*/
private void init() {
frameAnimation = (AnimationDrawable) getBackground();
post(new Runnable(){
public void run(){
frameAnimation.start();
}
});
}
/**
* 开启动画显示
*/
public void startAnimation() {
frameAnimation = (AnimationDrawable) getBackground();
post(new Runnable() {
@Override
public void run() {
frameAnimation.start();
}
});
}
/**
* 关闭动画显示
*/
public void stopAnimation() {
post(new Runnable() {
@Override
public void run() {
frameAnimation.stop();
}
});
}
}
2、布局文件
<com.tecsun.tsb.res.widget.AnimImageViewLoader
android:id="@+id/aiv_take_id_card_pic"
style="@style/style_wrap_content"
android:layout_alignTop="@id/iv_id_card_take_pic_main"
android:background="@drawable/anim_id_card_positive_pic" />
3、在代码中的调用
AnimImageViewLoader aivIdCardPic = xFindViewById(R.id.aiv_take_id_card_pic);
aivIdCardPic.setBackgroundResource(R.drawable.anim_id_card_negative_pic);
aivIdCardPic.startAnimation();
4、R.drawable.anim_id_card_negative_pic文件内容
<?xml version="1.0" encoding="utf-8"?>
<!--图片动画-->
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@mipmap/ic_id_card_negative_01" android:duration="300"/>
<item android:drawable="@mipmap/ic_id_card_negative_02" android:duration="300"/>
<item android:drawable="@mipmap/ic_id_card_negative_03" android:duration="300"/>
<item android:drawable="@mipmap/ic_id_card_negative_04" android:duration="300"/>
<item android:drawable="@mipmap/ic_id_card_negative_05" android:duration="300"/>
<item android:drawable="@mipmap/ic_id_card_negative_06" android:duration="300"/>
</animation-list>
